Looking good B! Beyoncé Knowles arrives at Michelle Obama's fundraiser tonight in New York City

She gave birth to her first child just over two months ago, but Beyoncé Knowles looks like she's already back to her pre-pregnancy shape. The 30-year-old singer looked stunning in a figure-hugging navy blue Victoria Beckham dress tonight as she stepped out in Manhattan to attend a fundraising event hosted by First Lady Michelle Obama. Her stomach looked unnaturally flat for a woman who just gave birth, but Beyoncé hasn't lost her curves.

She still showed off her stunning shape in the form-fitting Victoria Beckham frock, managing to look both sexy and elegant at the same time.She accessorised with two beaded necklaces, including one with a pendant shaped like an eagle. Her bright blue nail varnish, blue accents on her shoes and the colour of her dress were clearly a nod to her newborn, Blue Ivy.

Though her infant couldn't be with her for the swanky event, she was still there in spirit. Beyoncé did, however, join mother Tina Knowles at the cocktail reception and dinner inside Manhattan's Greenwich Hotel. The reception, which is being hosted by the First Lady, as well as Robert De Niro and his wife, Grace Hightower, will raise funds for Obama's re-election campaign.
